Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar
Kryger [21]

We can confirm that Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed vestigial.

<h3>What are vestigial features?</h3>

These can be thought of as features that belonged to ancestors of a specific species and are no longer needed, and thus have been reduced to functionless vestiges through many generations of evolution. The appendix is one such example in humans.

Which of the following intermediary metabolites enters the Krebs cycle and is formed, in part, by the removal of CO2 from a mole
asambeis [7]

Answer:

The correct answer will be option-D.

Explanation:

Before Citric acid cycle or Krebs cycle, an intermediate reaction takes place which converts the pyruvate into Acetyl CoA. This reaction is known as pyruvate decarboxylation as it produces Carbon dioxide.  

Coenzyme A reacts with pyruvate which causes the release of two oxygen atoms and one carbon to form CO₂ along with the reduction of  NAD+ to NADH and produce "Acetyl CoA."

Thus,  option-D is the correct answer.
